00:00 - 00:59 | hello student in this question we have to find the equation of a line hose slope and Y intercept are given ok first second and third before solving this question we need to know some concept related to this question ok let's suppose we have co-ordinate Axes is like this ok let's suppose this is x-axis this is y axis and this is origin now let's suppose we have a line which passes through this for dinner taxes like this ok and this point is that which is Y intercept ok now let's suppose the slope of this line is M then the equation of this line will wave equation of this line Railway |

01:00 - 01:59 | Y is equal to MX + c ok this is the concept but not here this she is what she is Y intercept ok this represents what Y intercept and if you will not is this is what this M represent the slope of this line slope of this line ok if if we will have slope and y-intercept we can write the equation of this line as Y is equal to X + a number of the question this is all about the concept to the question we have flop in the first question we have slope is -1 means in place of M we can write -1 and Y intercept is 3 |

02:00 - 02:59 | mens in place of C we can write three so first question solution of the first question will be Y is equal to MX + c right Vinod equation of line now this will be Y is equal to M we have given slope is -1 and y-intercept 3 right -1 hack free fire w y minus x y + 1 is equal to this will be the answer for the first equation first question now moved to the second question MS Word to Wi-Fi and we will be Y intercept will be -2 again we know |

03:00 - 03:59 | Y is equal to X + Y is equal to aim is to Wi-Fi right M is to Wi-Fi 2 by 5 x minus to write phase -2 will be what 5 Y is equal to 2 x 5 why not 5 I sorry this will be this will Wave Y is equal to 2 x minus 5 rate 5 Y is equal to 2 x minus 10 or you can say 2 x minus 5 Y is equal to 10 this will be the answer for second question |

04:00 - 04:59 | 3rd question 3rd question again the equation will be w Y is equal to AC and window M is M is 1 by 3 and Y intercept is to y3 1 by 3 X civil Bittu y3 can be written as Y is equal to this will be X + 2 by 3 ok aur you can say 3 Y is equal to X + 2 are you can say x minus 3 y x minus 3 Y is equal to minus 2 this is the answer for the third question thank you |
